【摘要】：随着信息技术的快速发展和物流技术的不断进步，电子商务在线渠道逐渐成为主流的交易渠道，越来越多的传统企业也开始拓展在线渠道，这样就不可避免地就遇到了在线渠道和传统渠道之间的共存和冲突问题，顾客也将很长时间内处于双渠道的市场购买环境。在这样的双渠道运营环境下，库存管理是其重要的环节之一，良好的库存控制可以使企业在激烈的市场竞争中保持竞争优势地位，而衡量库存管理水平高低的一个关键要素就是顾客服务水平，即现有库存可以满足顾客需求所占的比例。本文研究的是带有服务水平影响的双渠道库存模型理论。首先研究了传统渠道及在线渠道环境下的带有服务水平影响的库存控制理论，，为双渠道库存控制奠定基础。结合传统渠道和在线渠道的特点，分别构建具有服务水平约束的库存模型，进行模型求解和数值分析，研究表明服务水平与渠道需求之间应该具有更紧密的调节关系，这在双渠道环境下尤为明显。基于以上的研究成果，针对渠道需求、服务水平、价格之间的相互影响关系，提出了需求影响系数这一概念，并且研究了相应的计算方法。随后对双渠道库存管理模式进行了分类，分为分散管理模式和集中管理模式，分别对两种模式进行了模型构建和数值分析。研究表明不论是在分散管理模式，还是集中管理模式下，制造商和零售商企业可以通过构建的库存模型，预测和分析双渠道市场的竞争形势和各个渠道库存的变化情况，同时根据该模式可以计算出每个订货周期内的最佳订货批次以及单位时间的最佳利润值，最后还进行了需求不确定性灵敏度分析研究，获得了相应的结论。
[Abstract]:With the rapid development of information technology and the continuous progress of logistics technology, e-commerce online channel has gradually become the mainstream trading channel, and more and more traditional enterprises have begun to expand online channels. In this way, the coexistence and conflict between online channel and traditional channel will inevitably be encountered, and customers will be in the market environment of double channel for a long time. In such a dual-channel operating environment, inventory management is one of its important links, good inventory control can enable enterprises to maintain competitive advantage in the fierce market competition. And one of the key elements to measure the level of inventory management is the level of customer service. That is, the proportion of the existing inventory can meet the customer demand. This paper studies the dual-channel inventory model theory with the influence of service level. Firstly, the paper studies the impact of the traditional channel and online channel environment with the service level. Inventory control theory, Combined with the characteristics of traditional channel and online channel, the inventory model with service level constraint is constructed, and the model is solved and analyzed numerically. The research shows that there should be a closer regulatory relationship between service level and channel demand, which is especially obvious in dual channel environment. Based on the above research results, this paper puts forward the concept of demand influence coefficient in view of the interrelation among channel demand, service level and price. And the corresponding calculation methods are studied. Then the dual-channel inventory management model is classified into decentralized management mode and centralized management mode. The two models are constructed and analyzed numerically. The results show that both manufacturers and retailers can build inventory models through decentralized management or centralized management. The competitive situation of the double channel market and the change of the inventory of each channel are predicted and analyzed. According to the model, the best order batch and the best profit value per unit time can be calculated according to the model. Finally, the sensitivity analysis of demand uncertainty is carried out, and the corresponding conclusions are obtained.
